Answer» Answer: We have to find the TOTAL energy of the system:- we know that f = degree of freedom as oxygen is a diatomic gas diatomic gas degree of freedom f₁ = 5 monoatomic gas degree of freedom f₂ = 3 These are the degree of freedom of oxygen & ARGON For a gas , the formula is :- U = μN = μ U = 2 × 5 × + 4 × 3 × U = 5RT + 6RT U = 11 RT Hence the total energy of the system is 11 RT . Hope it Helps |
